- How to Apply
-
The foundation accepts unsolicited requests through a two-step process. Organizations begin with a one-page letter of inquiry describing their mission and services, the project, total project cost, other sources and amounts of support, project schedule, and IRS tax-exempt status. If the inquiry fits the guidelines, the foundation sends an application; completed applications go to the trustees for review. Applicants are asked not to request a specific grant amount, and the board determines the award level. The foundation requires progress reports for successful grants and generally will not consider another application from an organization until the original grant has been used successfully and a reasonable period has passed.
- Review Cycle
- The board meets quarterly and acts on applications received during each quarter. Board decisions are final.
